I often modify several files at once and after modifying I would
have to do

:w <RETURN>
:n <RETURN>

to get to the next file, so :wn is a shortcut for this, as all :w...
commands are, like :wq, :wq!, ...

At the first sight it looks difficult to write code, that does this
trick in an efficient manner without wasting too much precious bytes.

So after thinking about it, the patch for :wn isn't really necessary,
we would have to implement the "previuos" set of commands also a.s.o.

I agree with this.
But I'll have a look about how to get a little bit more comfortable
version done, which lets you do some vim-thingys I really like and
make them optional.

Hm?
